OpenMage magento-lts before 20.18.2 and 21.0.0-beta pre-releases before 21.0.0-beta3 generate customer email-confirmation keys with md5(uniqid()) and customer and administrator password-reset tokens with the non-cryptographic uniqHash(). Unauthenticated attackers can brute-force the roughly 20-bit confirmation key via the unrate-limited confirmAction endpoint to log in as pending customers, or predict administrator reset tokens after recovering generator state.
